Hi guys, I recently picked up a Haenel Model 1900 in 9x57mm, pre-1912 and indicated for a 2.9 g. powder charge. Does anyone know what bullet weight the sights are likely regulated for (using the powder charge as an indication), and/or what the typical loading was in this 1900-1912 period? Also, is this particular model typically a 0.354" or 0.356" bore? Thanks!
